One vendor we looked at sells a guest post for $375. A dedicated link building agency on this list says a typical campaign starts at $3,700 a month on a six-month contract. That's roughly a 10x gap, and the cheaper option looks identical on a monthly report. That's exactly why link building is where SaaS SEO budgets most often go wrong.
Search "SaaS link building agency" and half the results are price lists: a guest post here, a DR 60 placement there, a "niche edit" on a page that already ranks. Those are link sellers. They're cheap, they scale, and search engine spam policies treat bought links that pass ranking credit as link spam. A real link building agency works the other way round. It builds something worth citing (original data, a useful tool, an expert source) and pitches it to editors who decide for themselves whether to link. You pay for the work, not the link.
Six agencies made this list because we could verify they sell earned links, not placements. We checked each firm's site, its Clutch reviews from the last 12 months and its public posts for paid links, private blog networks and link packages. Each entry ends with an opinion and a "skip if," and the agencies we left out are named too, because here the exclusions say as much as the picks.
TL;DR: the verdict
Miraa, for B2B SaaS that wants digital PR tied to internal links and commercial pages, with link building included in plans from $2,500 a month. It rules out purchased insertions and link quotas on its own page.
Siege Media, for funded SaaS brands that can pay for research-led content and PR. Its most common Clutch project size is $50,000 to $199,999.
Page One Power, if you want a pure link building agency with a contracted link quota, from $3,700 a month.
The rest: Stratabeat if you want authority building bundled with SEO, GEO and content at $15,000+; Grizzle for content-led PR from $6,000 a month; Reboot Online for UK and European teams that want data-led PR with a link KPI.

Link builder or link seller? How to tell
Most agencies call themselves "white hat." That word doesn't tell you much, and the stakes are real: Google classes bought links that pass ranking credit as link spam under its spam policies. These signals tell you more.
Signs of a link seller
A price per link or per placement on the website, often tiered by DR or DA
"Niche edits" or "link insertions" into existing articles
Guest post packages with a guaranteed domain rating
A "publisher network," "partner network" or inventory you pick from
Packages for "grey niches"
When an agency guarantees a placement on a site it doesn't own, someone is usually being paid. That's the core problem.
Signs of a link builder
It sells campaigns, research or content, and the links come from coverage
It can show the asset that earned each link
It talks about editors choosing to link, not about inventory
It'll tell you when you have nothing worth pitching yet
There's a gray zone. Some legitimate agencies guarantee a link quota by contract, because they've done enough campaigns to forecast results. That isn't the same as buying links, but ask how the quota is met when a campaign underperforms.
How we chose the six
The five agencies after Miraa had to pass four tests. The evidence came from their own sites, review profiles and public posts:
No sign of paid links: We searched its site for per-link pricing, guest post menus, niche edits, link insertions and publisher inventories. We also read its last 12 months of Clutch reviews for descriptions of those tactics.
Earned-link method: A described approach based on digital PR, research, expert sourcing or content assets.
B2B or SaaS relevance: B2B or software clients, or a B2B-specific service.
Recent proof or pricing: Clutch reviews dated October 14, 2025 or later, or a published price.
Clutch ratings are as shown on October 14, 2026. Averages include older reviews; we only describe reviews from the last 12 months. Several agencies here have no recent reviews, and we say so.
Who we left out, and why
These agencies came up in our research and didn't make the list:
uSERP: A March 2026 Clutch review says the team "built guest posts and niche edits" for the client. Niche edits are usually paid insertions into existing articles, and a third-party review describes its placements in terms of guaranteed DR ranges. We couldn't confirm those placements are unpaid, so we left it out.
Editorial.Link: Its homepage lists guest posting at $375 and says it secures links "through publisher relationships." That's a placement product.
Authority Builders: Sells guest post services from a publisher inventory, including "Grey Niche" packages.
FATJOE: A 2026 roundup lists a $600 package for five links. Packaged link counts at a fixed price point to placements.
SAASY LINKS: Sells DR 50+ placements from what it calls 3,500+ editorial relationships. It says it doesn't use marketplaces, but we couldn't confirm the placements are unpaid.
Fractl: A February 2026 Clutch review from Terakeet says Fractl's team "leverage their extensive network of publishing partners to get exclusive content published on their sites for brand awareness and link authority that supports our client’s domain." That's the same publisher-network standard we used to cut SAASY LINKS, so Fractl is out too, despite strong recent reviews of its digital PR work.
NeoMam Studios and Digitaloft: Both describe earned-link methods, but neither passed our fourth test. NeoMam's newest Clutch review is from 2019, Digitaloft has no Clutch profile we could find, neither publishes pricing on its own site (NeoMam's Clutch profile lists only a $10,000+ minimum), and we found no dated client evidence from the last 12 months on either site.
Search Intelligence and Verve Search: We couldn't verify either: one domain showed a parked page and the other's site returned an error when we checked, and neither had recent Clutch reviews.
Leaving an agency out doesn't mean it's acting in bad faith. It means there wasn't enough evidence on its own site, in its reviews or in its public posts to confirm it sells earned links only.
Link method, price and proof compared
Agency | Link method (per its site) | Paid-link check | Pricing | Reviews (Clutch, last 12 months) | Clients and proof |
|---|---|---|---|---|---|
Miraa | Digital PR plus internal links from performing pages | Rules out purchased insertion and quotas on its own page | $2,500 / $3,500 / $5,000 a month, on its site | No profile yet | Clients include Salesforge, Leadsforge, Icypeas, Upsolve; Forge study named, three anonymized |
Siege Media | Research, surveys, content assets, press pitching | No per-link pricing found | $5,000+ minimum on Clutch | 4.9 from 48; two in window | Intuit, Asana, Zendesk on Clutch |
Page One Power | Manual outreach, six link types, digital PR | Site says "not link networks or PBNs" | From $3,700/month by quote; six-month initial contract | 4.7 from 17; one in window | Healthline, Hyatt, QuickBooks, Atera |
Stratabeat | Original research, promotion, bylines, Reddit | No per-link pricing found | Inside packages: $15k to $21k/month (Scale) or from $22k/month (Dominate) | 5.0 from 13; six in window (none about links) | B2B SaaS case studies |
Grizzle | Research, journalist outreach | No per-link pricing found | Digital PR from $6,000/month | Clutch: not yet reviewed | Pipedrive, Semrush, PandaDoc |
Reboot Online | Data-led digital PR | No per-link pricing found | From £3,500/month, with a guaranteed minimum link KPI | Clutch: not yet reviewed | AIPRM, BrokerChooser, Resume.io |
1. Miraa
Miraa works with B2B SaaS and AI companies, and links are one part of a wider SEO and AEO program. The four tests apply to the five agencies after it. Miraa's link building page frames the service as two halves: "One you control. One you can only earn."
On your own domain, it means pointing internal links from your strongest existing pages toward the ones that should start a sales conversation; the page calls this "the half teams skip because it is less dramatic than a new referring domain." Off your domain, it means digital PR: pitching relevant publications and practitioners "to describe something true." That work sits next to Miraa's SEO content service, because a pitch needs a page worth citing. The page is explicit about what's excluded: "No score, no quota, no purchased insertion." It also says "Placement is not guaranteed. Editors decide." If there's nothing to pitch yet, the first work is a page with a point of view, not outreach.
Services
Link building is one of ten Miraa services:
Product-led SEO: product, integration and use-case pages that links can point to.
Content-led SEO: topic plans that include research and opinion pieces worth citing.
Technical SEO: making sure linked pages can be crawled and indexed.
On-Page SEO: internal links and on-page fixes that pass authority to commercial pages.
SEO Site Migration: keeping earned links working when URLs change.
SEO Website Recovery: diagnosing traffic losses, including ones tied to a poor link profile.
AEO/GEO: getting cited and described accurately in AI answers.
Content Writing: written pages and articles.
Link Building: digital PR and outreach for earned links, with no purchased insertions.
Agentic SEO/GEO: AI agents used for research, prospecting and monitoring.
Pricing
Nothing is priced per link. Miraa's three plans cost $2,500, $3,500 and $5,000 a month (Basic Growth, Growth+ and Hyper-Growth). Link building is part of the broader B2B SaaS SEO program, not sold per link.
Reviews
No Clutch or G2 profile found.
Clients
Named clients include Salesforge, Leadsforge, Icypeas and Upsolve. Miraa doesn't publish link counts, by design, so its output can't be compared on volume. Its four case studies don't isolate link building either. The one named study, for Salesforge and four sibling products, credits a bottom-funnel content engine and a split keyword map for clicks rising 117.7% to 75,416 a quarter (Apr–Jun 2025 vs May–Jul 2026); the three anonymized ones mention LinkedIn amplification and community work rather than link campaigns.
Summary
Miraa's approach is the most commercially minded here: earn coverage, then route that authority through internal links to the pages that can turn a visit into a demo. Ruling out purchased insertions and quotas in writing is exactly what you want to see.
The cons: you can't judge its link work on public evidence, because no case study reports links. There are no third-party reviews. And link building is bundled into a broader plan, so if you only want a link campaign, you'll pay for SEO work you may not need.
The natural client is B2B SaaS teams that care more about where links land than how many there are. If you need a guaranteed number of links per month, or a standalone link campaign, it's probably not the agency for you.
2. Siege Media
Siege Media is a content and GEO agency whose links come from research and content assets rather than outreach for its own sake. Clutch's AI summary of its reviews lists "Impressive Link Building Results" as a theme.
Services
Per Clutch and its site: content marketing, SEO and GEO consulting, digital PR, affiliate partnerships and Reddit marketing. A recent client describes monthly surveys turned into articles, with Siege pitching press to secure coverage. That's the model: make data, then pitch it.
Pricing
Not published. Clutch lists a $5,000+ minimum project, $100 to $149 an hour, and $50,000 to $199,999 as the most common project size.
Reviews
Of Siege's 48 Clutch reviews (4.9 average), two fall within the last 12 months:
August 31, 2026 (5.0): An online therapy platform's content director listed backlinks and citations were part of the goal. The engagement combined monthly surveys, articles and press pitching, and the reviewer reported AI visibility for tracked prompts rising more than 400%.
July 10, 2026 (4.5): Pacaso's director of paid digital advertising praised Siege's organization over a long content engagement. This one is about content more than links.
Clients
Its Clutch profile lists Intuit, Asana, Zendesk, Quicken Loans and Chime.
Summary
Siege is the strongest research-led PR shop on this list, and links come as a byproduct of coverage. Its typical project size says who it's built for, and only one of its two recent reviews is about links.
The natural client is funded SaaS brands with budget for research, surveys and press pitching. If you're a startup that needs a handful of links on a small budget, it's probably not the agency for you.
3. Page One Power
Page One Power calls itself "SEO's Original Custom Link Building Agency" and says it has worked in link building for 15 years.
Services
Its homepage describes six link types, including foundational and industry links, earned media links, editorial links and expert links, and adds digital PR and internal linking. Its stated rules:
"100% manual outreach to publishers we've vetted"
"Real editorial placements, not link networks or PBNs"
"White-hat work that compounds for years"
It also says: "If you're looking for the cheapest link building option, we're not it."
Pricing
Custom. Its custom link building page says campaigns need an initial six-month contract, then can go month-to-month, and that it guarantees a link quota based on the contract. The same page says a typical campaign starts at $3,700 a month, with each campaign scoped to budget.
The guaranteed quota is the one thing to probe. Ask how they meet it when outreach for a campaign comes in light.
Reviews
Clutch shows 4.7 from 17 reviews. One is from the last 12 months: in February 2026, a senior content strategist at a university gave a 4.5 for backlink reclamation, link acquisition and a PR pitch after a rebrand, and said the work contributed to increases in organic traffic and conversions.
Clients
Its homepage names Healthline, Hyatt, QuickBooks and Atera. Atera and QuickBooks are software brands.
Summary
Page One Power is the only pure link builder here, with 15 years in the field and a contracted quota. The six-month initial contract is a real commitment, and it has just one Clutch review from the last 12 months.
The natural client is teams that want a dedicated link agency with predictable output. If you want links as part of a content or PR program, or can't commit for six months, it's probably not the agency for you.
4. Stratabeat
Stratabeat is a B2B SEO, GEO and content agency. Link building at Stratabeat sits inside a service it calls "Authority Building & Digital PR."
Services
Its authority building page lists original research, content promotion, editorial placements, executive bylines and guest posts, influencer collaboration, Reddit marketing and customer review optimization. It argues that "A single well-promoted piece of original research can drive backlinks, press coverage, speaking opportunities, social shares, and AI citations for months."
Executive bylines and guest articles are legitimate when the publication chooses them on merit. Ask Stratabeat whether any byline placements involve payment, as with any agency that offers guest posts.
Pricing
Its published packages put authority building and digital PR inside its Scale package ($15,000 to $21,000 a month) and its Dominate package (from $22,000 a month). It's not sold on its own.
Reviews
Clutch shows 5.0 from 13 reviews, six of them from the last 12 months. All six are for SEO, content, AEO or web work rather than link building, so they tell you more about the bundle than about the authority-building piece. Two examples: in February 2026, a marketing specialist at LBMC, a professional services firm, said Q4 website opportunity revenue rose 500% year over year and that the team "doesn't do fluff work to grab a buck." In January 2026, WellSaid's head of marketing reported organic traffic up 30% and conversions up 45% after an SEO and AEO audit. None of the six mentions guest posts, placements or publisher networks.
Clients
Its homepage cites a B2B property management SaaS company where organic traffic rose 123% in a year. The client isn't named.
Summary
Stratabeat's authority building only comes inside $15,000+ packages, and none of its six recent reviews is about links.
The natural client is B2B SaaS that wants authority building bundled with SEO, GEO and content. If you're early-stage, or want link building on its own, it's probably not the agency for you.
5. Grizzle
Grizzle sells "Organic Growth Systems for SaaS Companies." Its digital PR service describes "a content-led digital PR methodology."
Services
Digital PR built on content and research, with journalist outreach, aimed at AI search, brand building and thought leadership. Its homepage features a Pipedrive case study on an organic content program.
The homepage also lists guest placements for founder programs and "partner network distribution," described as tapping "Grizzle's network of editors, content creators, and media relationships." We found no price per placement or payment language, so Grizzle stays on the list, but this is the same signal the checklist above warns about. Ask how those placements are earned.
Pricing
Its digital PR page says plans start at $6,000 a month. When we checked, it also said it was "currently accepting 3 new customers for July 2026," so the capacity note looked out of date.
Reviews
Its Clutch profile says "Not yet reviewed." We didn't find recent reviews elsewhere.
Clients
Its site names Pipedrive and SmileBack in case studies, and its homepage also lists Semrush, Tipalti, Tide and PandaDoc.
Summary
Grizzle pairs content-led PR with a visible $6,000 floor and well-known SaaS clients. It has no Clutch reviews yet, and its capacity note looked out of date when we checked.
The natural client is SaaS companies that want a content-led digital PR program with a published starting price. If you need independent reviews before you sign, it's probably not the agency for you.
6. Reboot Online
Reboot Online is a digital PR and SEO agency that publishes a lot of its own research. An X post in April 2026 cited its Digital PR Statistics 2026 report for an average domain rating of 61 on earned coverage.
Services
Data-led digital PR campaigns, technical SEO, GEO and content. Its homepage says it earns "hyper-relevant links through Digital PR and AiPR." Its digital PR page lists a "Best Use of Search - B2B (SEO)" award.
Pricing
Its digital PR page says most retainers start at £3,500 a month and come with a "guaranteed minimum link KPI" agreed before you sign. Like Page One Power's quota, ask how Reboot meets that minimum when a campaign underperforms. It also offers a digital PR cost calculator.
Reviews
Its Clutch profile says "Not yet reviewed." One third-party directory lists guest posting among its services; Reboot's own site sells digital PR, and we found no placement menu or per-link pricing there.
Clients
Testimonials on its digital PR page include AIPRM, BrokerChooser and Resume.io.
Summary
Reboot publishes its own PR research and puts a minimum link KPI in the contract. With no Clutch reviews, ask how it meets that minimum when a campaign underperforms.
The natural client is UK and European SaaS teams that want data-led PR with agreed link targets. If your market is mainly the US, it's probably not the agency for you.
What good B2B link building looks like
B2B SaaS link building is harder than consumer link building. Journalists cover consumer surveys about sleep and money. Few cover your API rate limits. That shapes what works.
Data that buyers and editors care about
Original surveys of your buyer persona, benchmarks from anonymized product data, or a study of your category. Siege Media and Reboot Online both build programs around this.
Expert sourcing
Your founder, CTO or head of security answering journalist requests in their field. It earns fewer links than a viral study, but they tend to be more relevant.
Useful tools
Calculators, templates and free utilities that other sites link to because they're useful. These keep earning links long after launch.
Links to the right page
Most B2B coverage links to the homepage or a news post that expires. A good agency builds an internal link path from the page that earns coverage to the page that converts. For many SaaS sites that page is a comparison or alternatives page, which the comparison pages guide covers. It's the half of link building Miraa's link building page says teams skip.
Relevance over metrics
A link from a publication your buyers read is worth more than a high-DR link from a site they've never heard of. That's also the kind of reference AI tools are more likely to draw from when they describe your category.
Pricing models and what they tell you
Model | What it usually means | Risk |
|---|---|---|
Price per link | You're buying a placement | High: likely paid links |
Guaranteed DR or DA placements | Inventory-based placement | High |
Retainer with a link quota | Agency forecasts output from campaigns | Medium: ask how shortfalls are handled |
Campaign or retainer with no quota | Links depend on coverage | Lower risk, less predictable |
Bundled with SEO or content | Links as one lever among several | Depends on the bundle |
The cheapest option is almost always per-link. Earning a link takes research, design and outreach time, while buying one takes a payment.
If you're evaluating link builders, here's what to watch out for
Link building is the part of SEO where a cheap shortcut looks most like the real thing on a monthly report. Watch for these red flags:
Hesitation on payment. Ask directly: do you ever pay publishers, directly or through a partner, for a link or placement? An agency that hesitates has answered.
No asset behind the links. Every earned link should trace back to a story, study, tool or expert quote. Ask to see the asset that earned each link in a recent campaign.
Metrics instead of readers. If target publications are picked by DR alone, not by what your buyers read, you'll get links that look good in a spreadsheet and do little else.
Links to the homepage only. Ask which pages on your site the links will point to, and why. Coverage that never reaches a commercial page leaves value on the table.
A quota with no shortfall plan. A contracted quota can be legitimate, but ask what happens if a campaign earns fewer links than forecast. "We make it up" can mean "we buy them."
"Partner network" or "publisher relationships" language. These phrases are how several of the excluded agencies described placement products. Ask how each placement is earned.
Reports full of new referring domains you've never heard of. Ask for the list of linking sites each month and open a few. If they're sites with no real audience, stop.
Nobody owns internal links. Ask who adds links from coverage pages to commercial pages. If it's no one, much of the authority you paid for stays stuck.
Questions to bring to every call:
Do you ever pay for a link or placement, directly or through a partner?
Can you show the asset or story behind each link in a recent campaign?
Which pages on my site will links point to, and why those?
What happens if a campaign underdelivers?
How do you choose target publications?
Who owns the internal links from coverage to commercial pages?
How to read a monthly link report
Even with a good agency, you'll want to check the work yourself. A useful monthly report lets you answer four questions in a few minutes:
Start by asking where each link came from. Every link should come with the linking URL, the publication and the campaign or asset that earned it. If the report only shows a count and an average domain rating, ask for the full list.
Next, ask whether your buyers would read that site. Open a sample. A trade publication, an industry newsletter or a well-known practitioner's blog is what you're paying for. A site full of unrelated guest posts on every topic is a warning sign, whatever its metrics say.
Then check where each link points. Links to research pages and tools are normal. What matters next is whether those pages link on to your comparison, integration or plan pages.
Finally, ask whether anything is changing downstream. Over a few months, the pages that receive links, directly or through internal links, should start to rank better for the terms you care about. If links pile up and nothing moves, the problem may be the target pages, not the links.
How link building connects to AI search
Links matter for AI search too, in a slightly different way. An AI answer about your category draws on what multiple sources say about you. Coverage in publications your buyers trust gives those systems a consistent description to draw from. Paid placements on low-quality sites don't help that, and they carry spam risk in Google.
If AI visibility is a goal, read what AEO is and the AEO vs SEO comparison. For a broader view of agencies that do content and links together, see the list of B2B SaaS SEO agencies.
A realistic timeline
Earned links arrive in bursts, not a steady drip. A research campaign can take weeks to produce, then tends to earn most of its coverage soon after launch, with a long tail after that. Expert-sourcing work is steadier but smaller. That's why the agencies on this list that sell retainers tend to ask for several months up front, and why a single month's report says little on its own.
Judge a link program over two or three campaigns. By then you should be able to see which assets earn coverage, which publications respond, and whether the pages you care about are moving.
When link building isn't your first problem
Links get blamed for a lot of ranking problems they didn't cause. Our B2B SaaS SEO guide shows where links sit in the order of work. Before you sign a six-month link contract, check three things.
Can the target page rank at all?
If the pricing or comparison page you want links for renders client-side, is buried four clicks down or fights two near-duplicate URLs, no amount of outside links will fix it. That's a technical and structure job first.
Is there anything to pitch?
Editors link to data, definitions, tools and opinions with evidence. If your blog is product announcements, a link agency will either spend months building an asset with you or reach for shortcuts. Ask which one it plans to do.
Do you already have authority you're not using?
Many SaaS sites have strong pages, often old research or a popular template, that don't link to anything commercial. Internal links from those pages are the cheapest authority you'll ever get, and they're fully in your control.
If all three check out, link building is probably the right next investment. If not, fix those first and the links you earn later will do more.
How to choose: start from your situation
If you want a dedicated link agency with a contract and predictable output, pick Page One Power.
If you have budget for research and want coverage in major outlets, pick Siege Media.
If you sell mainly in the UK and Europe, pick Reboot Online.
If you want PR led by content and a visible starting price, pick Grizzle.
If you're already buying a large SEO and GEO program, pick Stratabeat.
If you want links pointed at the pages that convert, inside a broader SEO plan, pick Miraa's link building service.
And if the target page can't rank, there's nothing to pitch, or strong old pages don't link to anything commercial, fix that before hiring anyone (see above).
Whichever you choose, apply the inspection test. Every agency here sells something you can inspect: the research, the asset, the pitch and the coverage. If you can't see those, you're buying placements.
